Mr. Imani wants to purchase paper and notebooks for his classroom. At Dollar Discount he can buy packs of paper, p, for $1.25 each and notebooks, n, for $2.50 each. This is modeled by 1.25p + 2.50n. Evaluate for p = 10 and n=30 to find how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks. (1 point)

Well, Mr. Imani must really love paper and notebooks if he's buying that many! Let's help him out and do the math.
We know that packs of paper, p, cost $1.25 each, and notebooks, n, cost $2.50 each. So, to find the total cost, we multiply the cost per unit by the number of units of each item.
For the paper, Mr. Imani wants to buy 10 packs: p = 10. So the cost of the paper would be 1.25 * 10 = $12.50.
For the notebooks, he wants to buy 30 of them: n = 30. So the cost of the notebooks would be 2.50 * 30 = $75.00.
Now, to find the total cost of the paper and notebooks, we add these amounts together: $12.50 + $75.00 = $87.50.
So, the correct answer is $87.50. That's a lot of money for paper and notebooks! Mr. Imani must be building his own bookstore!
To find out how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks, we can substitute the values of p = 10 and n = 30 into the expression 1.25p + 2.50n and evaluate.
1.25(10) + 2.50(30) = 12.50 + 75 = $87.50
To find out how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks, we can substitute the values p = 10 and n = 30 into the expression 1.25p + 2.50n.
Let's calculate the cost:
1.25p + 2.50n
= 1.25(10) + 2.50(30)
= 12.50 + 75
= 87.50
So, the cost for Mr. Imani to purchase 10 packs of paper and 30 notebooks is $87.50.
Therefore, the correct response is:
$87.50
just do the substitutions as requested
1.25p + 2.50n = 1.25*10 + 2.50*30 = 12.50+75.00 = 87.50
and stop repeating the text -- so annoying
probably comes from copy/paste, so stop it.
